ABSTRACT Superconducting Quantum Interference Devices (SQUIDs) offer, without any doubt, the best performance to read out Transition Edge Sensors (TESs). However, considerations about costs and low temperature power dissipation have pushed our group to investigate alternate schemes that could provide satisfactory, if not comparable, performance. In particular, we are investigating the performance of a low temperature resonant circuit coupled with a room temperature FET voltage amplifier. We report and discuss here our preliminary analysis of the performance and optimization of this scheme and a preliminary experimental proof of concept.

    ABSTRACT: Large-format (>1000 pixel) arrays of transition-edge sensors are being developed for applications ranging from X-ray materials analysis to submillimeter (SCUBA-2, ACT, SAFIRE) and X-ray (Constellation-X) astronomy. Cryogenic multiplexing allows instrumentation of these large detector arrays with a manageable number of wires and readout channels. We describe a SQUID-based, time-division multiplexer for X-ray microcalorimeter arrays, including a three-stage SQUID amplifier chain and room-temperature digital-feedback electronics. The prototype system has passed two milestone tests. First, energy resolution of 6.6eV obtained from measuring 5.2keV joule-heat pulses was not degraded by multiplexing 2, 4, or 8 biased detectors. Second, 55Fe spectra obtained with four multiplexed detectors showed essentially the same resolution as those obtained from the same detectors while not multiplexed.

    ABSTRACT: We are developing transition edge sensors (TES) using single layer iridium (Ir) as the detector and deposited tin (Sn) as the absorber. We obtained good Ir devices with reproducible and uniform transition temperature around 120mK, transition widths of 1–2mK, residual resistivity ratio (RRR) between 1.8–3 and high sensitivity α. Our Ir films are obtained using radio frequency (RF) magnetron sputtering and photolithography. In this paper we present a full low temperature characterization of the Ir films.

    ABSTRACT: A series array of 100 DC SQUIDs has been fabricated using trilayer Nb-AlO<sub>x</sub>-Nb junctions. The SQUIDs are modulated with a common flux bias line and produce an output voltage swing of several millivolts across the array. The large output voltage will allow direct connection to room temperature electronics without the transformer coupling and resulting frequency limitations commonly associated with DC SQUID amplifiers. A bandwidth of DC to at least 175 MHz for a 100-SQUID array has been measured. The series array will be used as the output stage for a multistage integrated SQUID amplifier
